Abstract:

There is a rising concern for the safety of people from fire who cannot travel building emergency exit routes in the same manner or as quickly as expected of able people. One proposed solution for providing safety for persons with mobility limitations is the concept of an emergency elevator evacuation system (EEES). This paper presents information about the design of smoke control systems to prevent smoke infiltration into an EEES. Pressure differences produced when windows break both with and without wind can be significant, and the design of a smoke control system for an EEES needs to address these pressure differences. The paper identifies that wind data specifically for the design of smoke control systems is needed. The pressure fluctuations due to opening and closing building doors during fire situations can also be significant, and the design of a smoke control system for an elevator system needs to address these pressure fluctuations. An example analysis incorporating the pressure effects of broken windows, wind, and open doors illustrates the feasibility of designing smoke control systems for EEESs.
